INTRODUCTION: Network, according to Thesaurus Dictionary is “any complex, interlocking system”. According to the Dictionary web, for radio and television, “is a group of tramsmitting stations linked by wire or microwaves so that the same program can be broadcast”, for electricity, “is an arrangement of con- ducting elements, as resistors,capacitors, or inductors, connected by conducting wire”. In telecommunications, network is a system containing any combination of computers, printers, terminals, audio, visual display devices and telephones, interconnected by cables to transmit or receive information. A network can consist of two computers, or millions of computers connected with cables or optical fibers, that are spread over a large geographical area, such as telephone lines, active equipment, radio, television and all visual or communication devices. Internet is an example of a very large network. Cabling network standards are used internationally, published by ISO/IEC, NEC, CENELEC, NEMA, and the Telecommunications Industry Association (TIA). BICSI (Building Industry Consulting Service International) is a recognized independent trainer of computer structured cabling installers, with best practice documents and independent manufacturers, design and instal- lation, also plays a major role with industry leaders in developing and designing US standards. The main focus here is cabling installation standards, fiber optics and wireless systems, that is, the use of various standard cable systems for operating equipment such as computers, instruments, machinery, flow processes, and other applications including electric power cables and automation. However, automation systems are achieved by various means including mechanical, hydraulic, pneumatic, electrical, electronic and computers, and usually in a whole combination. Today extensive automation is practiced in practically every type of manufacturing and assembly process. Some of the larger processes include electrical power generation, oil refining, chemicals, steel mills, plastics, cement plants, fertilizer plants, pulp and paper mills, automobile and truck assembly, aircraft production, glass manufacturing, natural gas separation plants, food and beverage processing, canning and bottling and manufacture of various kinds of parts. ©2014 Jurandir Primo Page 2 of 111 www.PDHcenter.com PDHonline Course E449 www.PDHonline.org Robots are especially useful in hazardous applications like automobile spray painting. Robots are also used to assemble electronic circuit boards. Automotive welding is done with robots and automatic welders are used in applications like pipelines. The result has been a rapidly expanding range of applications and human activities. A computer-aided technology (CAx) is used to create complex systems, including Computer-aided design (CAD software) and Computer-aided manufacturing (CAM software). Programmable Logic Controllers (PLCs) are used to synchronize the flow of inputs from sensors and the flow of outputs to actuators and machinery. Human-machine interfaces (HMIs) are usually employed to commu- cate with PLCs and other computers. The International Society of Automation (ISA), founded in 1945, is a leading, global, nonprofit orga- nization, which sets the standard for automation, certifies industry professionals, provides educa- tion and training, publishes books and technical articles, and hosts conferences and exhibitions for automation professionals. ISA is also the founding sponsor of the Automation Federation (www. automationfederation.org). II. ELECTRIC TRANSMISSION LINES: Electric-power transmission is the bulk transfer of electrical energy, from generating power plants to electrical substations located near demand centers. In 1882, generation was with direct current (DC), which could not easily be increased in voltage for long-distance transmission. Other classes of loads (for example, lighting, fixed motors, and traction/railway systems) required different voltages, and so used different generators and circuits. Early DC generating plants needed to be within about 1.5 miles (2.4 km) of the farthest customer to avoid excessively large and expensive conductors. The competition between the direct current (DC) and alternating current (AC) by Thomas Edison and George Westinghouse respectively, in the late 1880s, was known as the War of Currents. At the conclusion of their campaigning, in the late 1890s, AC became the dominant form of transmission of power. In 1886, in Great Barrington, Massachusetts, a 1 kV alternating current (AC) distribution system was installed. That same year, AC power at 2 kV was installed at Cerchi, Italy, transmitted 30 km. In USA, at an meeting on 1888, Nikola Tesla delivered a lecture entitled “A New System of Alter- nating Current Motors and Transformers”, describing the efficient generation and use of polyphase alternating currents. The ownership of the Tesla patents, then, was the Westinghouse Company, which entered to offer a complete alternating current power system for both lighting and power. In Germany, the first transmission of three-phase alternating current using high voltage took place in 1891 during the international electricity exhibition in Frankfurt. A 25 kV transmission line, appro- ximately 175 km long, connected Lauffen on the Neckar and Frankfurt. Voltages used for electric power transmission increased through the 20th century. By 1914, fifty-five transmission systems, each operating with more than 70 kV, were in service. The highest voltage then used was 150 kV. The rapid industrialization in 20th century made electrical transmission lines and grids a critical in- frastructure item in most industrialized nations. The interconnection of local generation plants and small distribution networks, was greatly spread due the requirements of World War I, with large ©2014 Jurandir Primo Page 3 of 111 www.PDHcenter.com PDHonline Course E449 www.PDHonline.org electrical generating plants built by governments, to provide power to munitions factories. Later these generating plants were connected to supply civil loads through long-distance transmission. Transmission Grid: A transmission grid is a network of power stations and transmission lines. These networks use components such as power lines, cables, circuit breakers, switches and trans- transformers. Energy is usually transmitted within a grid with three-phase AC. Single-phase AC is used only for distribution to end users since it is not usable for large polyphase induction motors. In the 19th century, the two-phase transmission became used, but required either four wires or three wires with unequal currents. That time, the system started using transformers to step-up voltage to high-voltage transmission lines, and then to step-down voltage to local distribution circuits or industrial customers. Most transmission lines were high-voltage three-phase alternating current (AC), although single phase AC was sometimes used in railway electrification systems. Today, electricity is transmitted at high voltages (138 kV or above) to reduce the energy losses in long-distance transmission. Underground power transmission has a significantly higher cost and greater operational limitations but is sometimes used in urban areas or sensitive locations. Lower voltages, such as 69 kV and 26 kV, are usually considered sub-transmission voltages, but are occasionally used on long lines, with light loads. Voltages less than 33 kV are usually used for dis- tribution. Voltages above 230 kV are considered extra high voltage and require different designs compared to equipment used at lower voltages. Diagram of an electric power system; transmission system is in blue Since overhead transmission wires depend on air for insulation, the design of these lines requires minimum clearances to be observed to maintain safety. Adverse weather conditions, such as high wind and low temperatures, can lead to power outages. Wind speeds as low as 23 knots (43 km/h) can permit conductors to encroach operating clearances, resulting in a flashover and loss of sup- ply. Oscillatory motion of the physical line can be termed gallop or flutter depending on the fre- quency and amplitude of oscillation. Electric power can also be transmitted by underground power cables instead of overhead power lines. Underground cables take up less right-of-way than overhead lines, have lower visibility, and are

    Ethernet/Category 5 Network Cabling Guide Prepared by SJ Wilkinson (August 2002) Based on Steve DeRose’s Guide to CAT5 Network Wiring (See later Web Reference) Networks A Local Area Network (LAN) can be as simple as two computers, each having a network interface card (NIC) or network adapter and running network software, connected together with a crossover cable. Here the crossover cable would have a plug at either end to connect into the NIC socket at the back of each computer. The next step up would be a network consisting of three or more computers and a hub. Each of the computers is plugged into the hub with a straight-thru cable (the crossover function is performed by the hub). For a small network the straight-thru cables would have plugs at either end – one to connect to the computer and one to the hub. For larger networks wall cabling, wall sockets and patch cables are used. A CAT5 "patch panel" is used at the hub end where all your wires come together and provides a group of sockets for further cables. Straight-thru patch cables connect computers to sockets (jacks). Straight-thru wall cables connect sockets to the patch panel. Straight-thru patch cables connect the patch panel to the hub. Patch panels often make network cabling neater but are not essential as (a) wiring a plug is no harder than wiring a panel; (b) you still need cables to go from the panel to the hub; and (c) it adds extra connections, so lowers reliability. 1 Planning your Network Pick a location for your hub, preferably centred to keep cable runs shorter.

  • Getting Physical with Ethernet
    ETHERNET GETTING PHYSICAL STANDARDS • The Importance of Standards • Standards are necessary in almost every business and public service entity. For example, before 1904, fire hose couplings in the United States were not standard, which meant a fire department in one community could not help in another community. The transmission of electric current was not standardized until the end of the nineteenth century, so customers had to choose between Thomas Edison’s direct current (DC) and George Westinghouse’s alternating current (AC). IEEE 802 STANDARD • IEEE 802 is a family of IEEE standards dealing with local area networks and metropolitan area networks. • More specifically, the IEEE 802 standards are restricted to networks carrying variable-size packets. By contrast, in cell relay networks data is transmitted in short, uniformly sized units called cells. Isochronous , where data is transmitted as a steady stream of octets, or groups of octets, at regular time intervals, are also out of the scope of this standard. The number 802 was simply the next free number IEEE could assign,[1] though “802” is sometimes associated with the date the first meeting was held — February 1980. • The IEEE 802 family of standards is maintained by the IEEE 802 LAN/MAN Standards Committee (LMSC). The most widely used standards are for the Ethernet family, Token Ring, Wireless LAN, Bridging and Virtual Bridged LANs. An individual working group provides the focus for each area.

  • Cat 6 Cable: Copper's Last Stand?
    Cat 6 Cable: Copper’s Last Stand? Cat 6 Cable is craft intensive! Advanced Installation & service skills are a MUST. 1 Cat6 Cable: Copper's Last Stand? Nope, Not yet! 10Gig IP to the rescue! What is Category 6? Unlike earlier cabling standards Category 6 is a 200MHz classification. The Category 6 standard is an integral part of the 2nd editions of the ISO 11801, TIA 568A and En5017. Initially there were only two parameters proposed for Category 6. These were that any Category 6 solution must use the existing RJ45 plug and jack format. The second was that the Powersum ACR must be positive to 200 MHz. As the standards have developed, additional parameters have been added. These standards continue to be developed and represent the pinnacle of performance for structured cabling systems. The intention behind the Category 6 standard is to provide the state-of-the-art 4-pair cabling system. The different and more stringent handling requirements for Category 6 components demand additional training, even for installers well used to the demands of Category 5e installation practices. Time, care and a high level of technical expertise are essential when installing Category 6. Even slight variations in the termination of links can have a massive effect on the overall performance of the system. It is for these reasons, that it is essential to select an installer who has an existing track record of successfully installing Category 6. With the comprehensive backing of Molex, under the Certified Installer (CI) program, SMT has the experience and track record you need to be sure that your Category 6 solution will perform for you now and in the future.

  • Computer Ports
    Computer Ports In computer hardware, a port serves as an interface between the computer and other computers or peripheral devices. Physically, a port is a specialized outlet on a piece of equipment to which a plug or cable connects. Electronically, the several conductors making up the outlet provide a signal transfer between devices. The term "port" is derived from a Dutch word "poort" meaning gate, entrance or door. ETHERNET PORTS: Ethernet is a family of computer networking technologies for local area networks (LANs) commercially introduced in 1980. Standardized in IEEE 802.3, Ethernet has largely replaced competing wired LAN technologies. Systems communicating over Ethernet divide a stream of data into individual packets called frames. Each frame contains source and destination addresses and error-checking data so that damaged data can be detected and re-transmitted. The standards define several wiring and signaling variants. The original 10BASE5 Ethernet used coaxial cable as a shared medium. Later the coaxial cables were replaced by twisted pair and fiber optic links in conjunction with hubs or switches. Data rates were periodically increased from the original 10 megabits per second, to 100 gigabits per second. Since its commercial release, Ethernet has retained a good degree of compatibility. Features such as the 48-bit MAC address and Ethernet frame format have influenced other networking protocols. HISTORY OF ETHERNET: Ethernet was developed at Xerox PARC between 1973 and 1974.[1][2] It was inspired by ALOHAnet, which Robert Metcalfe had studied as part of his PhD dissertation.[3] The idea was first documented in a memo that Metcalfe wrote on May 22, 1973.[1][4] In 1975, Xerox filed a patent application listing Metcalfe, David Boggs, Chuck Thacker and Butler Lampson as inventors.[5] In 1976, after the system was deployed at PARC, Metcalfe and Boggs published a seminal paper.
